UNITE LANTERN-LOOKING DEVICE AND STANGHION.

Application filed August 25, 1923. Serial No. 659,356.

To all whom it may concern:

Be it known that I, ARTHUR A. SAMPSON, a citizen of the United States, residing at Plymouth, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Lantern-Locking Devices and Etanchions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a device for guarding and illuminating street excavations and the like, the device insuring the maintenance of the lighting elements in the position in which they are originally placed.

A. further object is to provide a supporting element or stanchion adapted to mount a lantern and also adapted to support rails or boards placed horizontally and serving as a barricade for guarding street excavations.

A still further object is to provide a device of this type which shall include a heavy base of concrete or the like, a standard or upright carrying a bracket for the horizontal elements of the barricade, and a lantern support and locking member comprising a base and a two-part clamp, assembled in the particular manner described below.

In the drawings forming a part of this application Figure 1 is a view of the device in side elevation, with a portion of the base broken away,

Figure 2 is a top plan view of that portion of the device in which the lantern is directly received and secured,

Figure 8 is a further view of the upper portion of the structure. 1

The upright or standard 10 includes a lower U-shaped element 11 embedded in a concrete base 12. It is obvious that the shape of element 11 is not important, if a proper support or anchor is provided. It is desirable that the base be surrounded by a metallic band 13, and that the base be sufliciently heavy to prevent the device from being easily overturned or carried away. A large number of lanterns are lost by contractors having occasion to make use of them for the purpose specified, and one of the objects of the present invention is to reduce this loss to a minimum.

A. bracket 14 extends outwardly and upwardly from element 10 and may be secured by brazing, welding, or in any other suitable manner. This bracket is intended to support rails, chains, or boards, two or more stanchions being provided for building a barricade of the kind used to guard trenches for water mains, and for other similar purposes.

The upper portion of the device includes a base 15 of spider-like form, and a twopart clamp formed of semicircular elements, pivoted at one side and adapted to be locked together at the other side. A central aperture 15 admits the reduced upper end of element 10, which is secured in any suitable manner as by heading the end or providing a nut or other securing element 15'.

Two of the arms 16 and 17 of the spider construction are upwardly turned into lugs which are spaced vertically and horizontally from the clamp, and the other two arms 18 and 19 directly mount and secure the clamp. Upturned end or lug 26 of arm 18 consti tutes a pintle for the hinge portion of the clamp, and upturned end or lug 19 is twisted to form a flat member provided with an aperture 21 for the purpose indicated below.

The semicircular elements 22, 23 of the clamp are provided with rolled ends such as 24, 25 encircling the pintle 26 providing a hinge for the clamp. The opposite ends of the clamp members are outwardly turned at 27, 28 and have apertures 29 and 30 for engagement by the hasp of a padlock 31, when apertures 29 and 30 are in registration with aperture 21. The elements of the spider-like base are spaced from the clamp suliiciently to permit the flange ot a lantern base to pass between them, and when the clamp is closed the lantern is secure against removal.

By insuring the continued operation of each source of illumination, fewer units are required, and the loss incident to the unauthorized removal oit lanterns, and failure to observe the excavations or obstructions, is greatly reduced.

What is claimed is:

A device of the class described comprising a base having upturned lugs, one of said lugs being formed into a pintle, another of members may swing thereover in opening said lugs being twisted into a securing porand closing.
